Filed: 1989-12-07
Abstract: PURPOSE:To charge an inspecting gas efficiently in a short time by making the back side of a membrane in a negative pressure state with vacuum suction and the like, and charging the inspecting gas into the part in the negative state. CONSTITUTION:When air in the back side 4a of a membrane 4 is discharged to provide a negative pressure state, a vacuum suction valve 7 is closed, an inspecting gas supplying valve 10 is opened, and an inspecting gas such as ammonius gas or halogen gas is sucked in from an inspecting gas supplying device 11 via a gas charging pipe 9.

Abstract: PURPOSE:To detect accurately the deterioration of a developer and prevent beforehand the deterioration or the like of a development performance and an image quality, by operating a blackening rate from an exposure time that is according to a picture signal, and comparing it with a reference value. CONSTITUTION:A laser 31 is modulated by a modulation portion 30, and outputs a laser beam forming an image on a photosensitive drum. By the way, as for a signal, a radiation time is counted at a counter portion 32, and addition is made at a memory portion 501. Comparison with a reference value is made at a comparison portion 502, and when an addition value surpasses the reference value, a supply signal is outputted to a supply means 51. Also, the radiation time is outputted to a toner deterioration detecting means 52, and addition is made at a memory portion 521. And, at an operation portion 522, a blackening rate is calculated from the radiation time addition value and a transfer material size signal. And, a comparison portion 523 compares this blackening rate with a reference value and decides if it is a toner low consumption quantity or not. That is, if the blackening rate is small, toner consumption is small, and it follows that a stirring time has become long by staying in a development counter and deterioration has been realized.

Inventor: NAKANE IKUROU
IPC: H01M10/05
Filed: 1989-12-08
Abstract: PURPOSE:To enhance the cycle characteristic of a battery by suppressing initiation of cracks at the Li/Al grain boundary in a neg. electrode. CONSTITUTION:A neg. electrode is made of an alloy represented by lithium- aluminum-X-Y, where X is either Mn or Cr, and Y is one of the group consisting of Be, Bi, Cd, Ge, Pb, Sn, and Tl. The alloy of X, Y metals with aluminum will have the metal structure of an eutectic or a peritectic type alloy. If this alloy and lithium are turned into one alloy, therefore, the X and Y metals will exist at the grain boundary, so that crack initiations in this part will be suppressed. This turns the neg. electrode active substance into particulate and prevents deterioration of the cycle characteristic.
